IRA O. STANT, OF DUBLIN, INDIANA, ASSIGNOR OF ONE-HALF TO CHARLES M. EVANS, OF DUBLIN, INDIANA.

TROLLEY-WHEEL.

Application filed March 3, 1908.

To all whom it may concern.

Be it known that l, Inn 0. STANT, a citizen I of the United States, resident of Dublin, in

the county of li ayne and State of Indiana, have made a c tain new and useful invention in Trolley heels and I declare the following to be a ruli, clear, and exact description of the same, such as will enable others skilled in the art to wh'ch it appertains to make and use the invention, reference being had to t e accompany ng draw rigs, and to letters or reference marked thereon, which form a part of this specification.

Figure l is a side view of my trolley wheel with the eccentric flange shown as raised in dotted lines. Fig 2 is a plan view of the invention. Fig. 3 is a section on the line 33, Fig. 2 with conductor wire omitted. at is an end view of one of the cone 'heel idlers. Fig. is a central vei al se *tion of a modified form of the invention.

The invention has relation to trolley wheels, having for its object the provision of means whereby the wheel will be automatically replaced upon or centered with respect to the wire conductor, without regard to Whether the car is going forward or backward, and without stopping the car.

.Yith this object in view, the invention consists in the novel construction and combination of parts, as hereinafter set forth.

In the accon p ,ving drau. gs, illustrating the invention the letter a, desig ates the usual trolley aid f, Z), the e sha )cd wheels constituting my invention, and which are arranged one at each side of the wheel a, -ll of such wheels bei mounted uponthe spindle (Z, having gs at its ends in the fork c, of the trolley pole.

Each cone shaped wheel 5), has a spiral groove f, therein, run Ir one direction and intersecting a spiral groove 9, rui'ining in the opposite direction. At diametrically opposite points at top and bottom of the cone wheel where the two spiral grooves intersect, the side walls of the grooves are extended inward or towards the upper or larger end of the cone wheel, as shown at i, 'i, whereby the cone wheel, the spiral groove of which the wire conductor, will be thrown slightly to one side or laterally deflected as sair extensions i, i", strike the same, and the spira groove leading towards the larger end of the cone and the trolley wheel proper caused to engage such conductor.

.1 ALL" Specification of Letters Patent.

Patented Feb. 9, 1909.

Serial No. $19,066.

At the upper or larger end of each cone wheel an eccentric flange j, is provided, which at its point j, of greatest eccentricity is about on a level with orit may be somewhat above the trolley wheel itself when the cone wheel is turned by the frictional action or contact of the wire conductor, so that when the cone wheel has been moved to cause the conductor wire to engage the portion of the spiral at the top thereof, a groove j of the flan e j, forming a continuation of the spirals f, and g, will engage the wire, which will be gradually raised by the eccentric flange until it escapes from the groove thereof and falls upon the trolley wheel. The groove j of the eccentric flange leads inward and becomes less deep towards the point of greatest eccentricity of the flange, as shown at 7 At the smaller end of the cone wheel an annular flange 7c, is provided, acting as a deflector to prevent the cone wheel in case of bounding from escaping from the wire entirely.

The cone wheels I), b, are idlers upon the spindle (Z, and inasmuch as the eccentric flanges thereof hang normally downward through force of gravity and their point of least eccentricity, shown at j, is in line with the inclined or conical surface of the wheel, no obstruction is offered to the passage of the trolley wheel from the wire conductor to a side line or switch thereof, or vice versa. in some cases the trolley wheel may be made in one piece with the cone wheel or rigidly secured. thereto, as shown in Fig. 5 of the drawings.

Having thus described my invention, what i claim as new, and desire to secure by Letters Patent is A trolley wheel having at each side thereof a cone wheel idler provided with intersecting spiral grooves running in opposite directions, the side walls of said grooves having inward deflecting extensions at the points of intersection, said cone wheel having at its larger end an eccentric flange provided with a groove communicating with said spiral grooves and leading towards the trolley wheel.

in testimony whereof I affix my signature, in presence of two witnesses.
